Don-Jo EL-103-RC Extended Lip Strike with Radius Corner, 2-1/4" x 3", 18 Gauge

The Don-Jo EL-103-RC is a commercial-grade Extended Lip Strike featuring a radius corner profile and precise 2-1/4" x 3" dimensions, constructed from durable 18-gauge (.050) steel for reliable performance in demanding door hardware applications. Designed with a single latch hole and an extended lip configuration, this strike is well-suited for commercial door installations where a clean, secure latch engagement is required. Available in a wide selection of finishes — including DU, 605, 609, 619, 622, 629, and 630 — to match virtually any door hardware finish specification. Note: the 3" width measurement is taken from the center of the screw hole to the end of the lip.

Key Features

  • Precise Dimensions: Measures 2-1/4" (height) x 3" (width), with the width measured from the center of the screw hole to the end of the lip for accurate installation planning.
  • Extended Lip Design: Extended lip configuration provides enhanced latch engagement and added door security for commercial applications.
  • Radius Corner Profile: Smooth radius corner (RC) design offers a refined aesthetic and reduces sharp edges for a professional finish.
  • Heavy-Gauge Construction: Manufactured from 18-gauge (.050) steel, delivering durability and long-term performance in high-use commercial environments.
  • Single Latch Hole: Features one latch hole, providing a clean and straightforward installation compatible with standard latch bolt configurations.
  • Broad Finish Selection: Available in seven finishes — DU, 605, 609, 619, 622, 629, and 630 — to coordinate with a wide range of door hardware specifications.

Don-Jo EL-103-DU-RC – Frequently Asked Questions

1) What size is the Don-Jo EL-103-RC strike, and how is the 3 inch measured?
The EL-103-RC extended lip strike measures 2-1/4 inches by 3 inches. The 3 inch figure is not the plate width in the usual sense: it is measured from the center of the screw hole out to the end of the lip. That matters when you are laying out the frame prep, because it tells you how far the lip runs past the fastener line rather than how wide a mortise you need. Corners are radiused (the RC in the model number).
2) What does an extended lip strike do that a standard strike doesn't?
The lip is the tab that runs off the frame toward the door face and guides the latchbolt in. On the EL-103-RC it is extended, which is what you want when the door is set back from the frame face, when a heavy stop or applied trim leaves the latch reaching, or when the latch is dragging on the jamb edge instead of riding onto the strike. A standard-lip strike on those openings lets the latch catch the frame. If your latch already rides cleanly onto a normal strike, you don't need the extra lip.
3) Is the Don-Jo EL-103-RC right for a hollow metal frame with square corners?
No. The EL-103-RC has radiused corners, so it drops into a frame prep with rounded corners. In a square-cut prep the round corners leave four visible gaps at the openings. Match the corner profile to the prep you already have: radius corner strike for a radius prep, square corner for a square prep.
4) Will one Don-Jo EL-103-RC strike handle a lockset with both a latch and a deadbolt?
No. The EL-103-RC is a single latch hole strike, so it takes one bolt. An entry with a separate deadbolt above the lever needs a second strike for the deadbolt, or a single T-strike cut for both. Check the door before ordering: one hole in the strike means one bolt in the door.
5) Is the Detex 92 strike kit a substitute for a Don-Jo EL-103-RC extended lip strike?
No, they solve different openings. The Don-Jo EL-103-RC is an extended lip strike, 2-1/4 inches high by 3 inches wide in 18-gauge (.050) steel with a single latch hole, mortised into the frame of a standard single door where the latch needs the lip carried out past the jamb. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series, supplied with tamper resistant fasteners for the inactive leaf of a pair. If the opening is a pair of doors and the strike mounts to the second leaf rather than the frame, the Detex 92 kit is the part to specify; for a single door with a frame-mounted strike, the EL-103-RC is.
6) What strike should I use when the latch has to catch on a pipe or round post instead of a flat jamb?
Use the Trimco 1260P, a pipe adapter strike from the Trimco 1260 Series, sold as the strike only. It is built to bring a latch keeper to a round section rather than a flat frame face. The Don-Jo EL-103-RC extended lip strike is a flat 2-1/4 inch by 3 inch plate in 18-gauge (.050) steel with one latch hole, and its extended lip is meant to bridge the gap on a conventional frame; it has no provision for wrapping a pipe. Match the strike to the surface it lands on -- pipe or post takes the 1260P, standard jamb takes the EL-103-RC.
7) What gauge steel is the Don-Jo EL-103-RC, and is it heavy enough for a high-traffic entrance?
18-gauge steel, .050 inch thick, and Don-Jo builds it as a commercial part rather than a residential one. That thickness is what keeps the lip from deforming when a latch is hitting it hundreds of times a day on a school corridor, a hospital wing, or a multi-tenant lobby. It is a strike plate, not a reinforcer, so it resists wear rather than forced entry.
8) What finishes does the Don-Jo EL-103-RC extended lip strike come in?
Eight: 605 bright brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless steel, 630 satin stainless steel, and DU duronodic brown coated. If you are standardizing a building, 630 is the usual match for satin stainless lever sets and 626-family hardware, and 605 pairs with bright brass trim. Order the strike finish off the lockset already on the door, not off the door itself.
9) For a commercial job standardizing on one strike across many single doors, which of the Don-Jo EL-103-RC, Detex 92 or Trimco 1260P is the one to stock?
The Don-Jo EL-103-RC is the one that repeats across ordinary single-door openings. It is a commercial extended lip strike, 2-1/4 inches by 3 inches in 18-gauge (.050) steel, sold in shelf packs of 10 and offered in DU, 605, 609, 619, 620, 622, 629 and 630 so one part number can be carried through an office, school, healthcare or multi-tenant building without changing the finish schedule. The Detex 92 Strike Kit is a double door kit in the Detex 90 Strike Series and applies only where the opening is a pair, and the Trimco 1260P from the 1260 Series is a pipe adapter strike for round sections. Both of those are opening-specific rather than a general frame strike.
10) Does the Trimco 1260P come with the fasteners, and how does that compare to ordering the Detex 92 or the Don-Jo EL-103-RC?
The Trimco 1260P pipe adapter strike is supplied as the strike only, so plan on sourcing the attaching hardware for it separately. The Detex 92 double door strike kit is furnished as a kit with tamper resistant fasteners, which matters where the strike is exposed on the leaf of a pair. The Don-Jo EL-103-RC is a 2-1/4 inch by 3 inch, 18-gauge (.050) extended lip strike with a single latch hole and ships in shelf packs of 10, so it is ordered by the pack for multi-door work rather than as a per-opening kit.
11) Does the Don-Jo EL-103-RC come with screws?
The EL-103-RC is sold as the strike plate itself, in shelf packs of 10. Plan on supplying fasteners and, on a wood jamb where you want the latch backed up, a separate strike box or reinforcer. The pack of 10 is aimed at re-keying or refinishing a run of doors at once rather than a single-door repair.
